The Liquid Crystal Displays (LCDs) are a type of flat panel display that uses liquid crystals for operation. They are relatively old technology but can be seen in clocks, laptops, computers, calculators, dashboards, and other electronic projects and devices because of their advantages over newer types of displays, including low power, low cost, and readability.

Board Design For part of my final project I want to make my own USB audio recording device. So I’ll try to develop all the necessary electronics this week. I have the analog circuitry I need from inputs week. But I don’t have a board ready to go with a USB-capable microcontroller (bit-banging will not suffice,
Lattice Semiconductor has introduced a new general-purpose FPGA family that has been developed to combine high I/O density, low-power, small packages and fast interfaces. [via] The Lattice Certus-NX series provides up to double the I/O density per mm 2 of similar FPGAs, and provides power savings, a small footprint, reliability, and instant-on performance. Devices in the family support

For a number of years now I’ve had a couple of high powered switching power supply units made by Power-One. They’re typically found in I.T. equipment and provide a single output rail of either 12 V or 48 V with a very high current rating. The other cool thing is that in the case of

Today I am going to show you how to make a pulse counter quickly with littlebits modules. This is a very fun and easy project to do and you can, for example, count the times a door opens, as was the case with our makerspace that we made a counter of these to count the

Determine the power absorbed by the VCVS in the figure. Solution: The VCVS consists of an open circuit and a controlled-voltage source. There is no current in the open circuit, so no power is absorbed by the open circuit. The voltage vc across the open circuit is the controlling signal of the VCVS. The voltage
